Hello! My friend Fari send me this suspecious message: 'MQDzqdor{Ix4Oa41W_1F_B00h_m1YlqPpPP}' and photo.png. Help me decrypt this!
I wish they'd fix that spelling mistake.

Suspicious, not suspecious.
hint for all: the code above uses the playfair method, and for PpPP. you know? in playfair every letter is a pair. that's how we can determine the original letter. but, in playfair, double-letters will be angled up left. if there is 1 letter then the letter remains. example: based on key in photo.png => original letter in cipher "K" is "K" but original letter in cipher "Kk" is "Aa". playfair learning reference for beginners -> https://en.wikipedia.org/wiki/Playfair_cipher

Cool puzzle, could have figured it out with out comments, but would have taken a bit. If you want a hint, all I can say is that this is a fair puzzle that is played a lot.
